Plot

After witnessing Cedric Diggory's death, Harry Potter is worried that things could get worse. As he and his cousin Dudley are walking home from the park they are attacked by Dementors and Harry casts a Patronus Charm to save them both from the Dementor's Kiss. An extremely baffled Dudley is taken back to Privet Drive accompanied by Mrs. Figg. A Howler from Mafalda Hopkirk of the Ministry of Magic|Ministry arrives for Harry and tells him he is expelled from Hogwarts School of Witchcraft and Wizardry for using magic in front of a Muggle. The Order of the Phoenix comes and rescues Harry and then takes him to 12 Grimmauld Place to stay, where he finds out that Hermione and Ron's family is there, too. Harry also has many nightmares about the events that had happened the previous year, including the death of Cedric Diggory and the rejuvenation of Voldemort. While at 12 Grimmauld Place, Harry's godfather Sirius Black mentions that Voldemort is after "something he didn't have last time." Then he finds out about the Order of the Phoenix organisation, which consists of Sirius Black, Severus Snape, Mr. Weasley, Mrs. Weasley, Professor Lupin, Tonks, Professor Moody, and many others. At the Ministry, Dumbledore defends Harry's actions. The Minister for MagicCornelius Fudge denies Harry's answer to his question, regarding what actually took place on the night in question, leading to further arguments. In the end Harry is cleared of all charges. Because Dumbledore reminds them that, expelling him from the school of using a charm to defend them against the dementors. It is not forbidden to use magic when you are under age if it is a matter of life or death.

As they arrive at Hogwarts they find out that Dolores Umbridge is the new Defence Against the Dark Artsteacher. She gives false information such as denying Lord Voldemort's return. When Harry tries to say that Voldemort has returned, she gives him detention and makes him write "I must not tell lies". She gives him a quill that engraves the words into his left hand. She later tries to sack Professor Trelawney, but is stopped by Professor McGonagall and Dumbledore. At the same time, Dumbledore distances himself from Harry, knowing that Harry's mind is connected to Voldemort and can see visions of Voldemort when he gets a big emotionally charge like happines or anger. Later on, Umbridge becomes the new headmaster, thus kicking Dumbledore out of his position and attempting to send him to Azkaban, which fails. Under the assumption that Dumbledore's Army is an organisation formed to undermine the Ministry. As headmistress, Umbridge bans many student activities and basically revokes student freedom. You can get the activities back if umbridge allows you to have a group bigger than 3 persons. The trio, along with many other Gryffindor, Ravenclaw, and Hufflepuff students, despise Umbridge very much, and realise that with Umbridge constantly watching them, they cannot get any learning of Defence Against the Dark Arts, and prepare themselves for the real world, the war against Voldemort and his Death Eathers. Harry, Ron, and Hermione decide to find a secret place in the castle where all willing students can come and learn of the Dark Arts defence. Neville Longbottom finds the Room of Requirement. They decide that Harry will be their new Defence Against the Dark Arts teacher. The students use the room to train for Dumbledore's Army, which is later found out by Umbridge (who had taken many of the acquaintances of Harry into questioning, and had illegally used Veritaserum on Cho (This isn't actually correct according to the books, but in the film they did it this way), who then revealed the Room of Requirement) and the Inquisitorial Squad (consisting of Draco Malfoy, Vincent Crabbe, Gregory Goyle, Pansy Parkinson, and a few others).

Harry has a vision of an attack on Arthur Weasley in the Department of Mysteries, and Dumbledore instructs Snape to give him Occlumency lessons in order to block his mind from Voldemort's influence. During the lesson, Harry is able to penetrate Snape's mind and see all his memories, including one where James Potter and Sirius Black, in their adolescence, are bullying Snape, and he sees why Snape despises his father so much. Harry, in turn, agrees that his father was acting in a behavior that Harry was not proud of. The Occlumency lessons causes Harry to push all his friends away from him. {C
Along with nine other Death Eaters, Sirius's deranged cousin, Bellatrix Lestrange, escapes from Azkaban prison.

During an exam, the Weasley twins (who dropped out of school to pursue a career as prank shop owners) revolt and set off fireworks in the Great Hall, causing chaos for Umbridge, but all the students except Slytherin are happy, including Professor Filius Flitwick. During this event, Harry has a vision of Sirius being tortured by Voldemort within the Department of Mysteries. Hermione points out that Voldemort may be only tricking him to lure him into his grasp, but Harry retaliates by saying that he is Harry's only family left. Harry, Ron, and Hermione rush to Umbridge's fireplace to alert the Order via the Floo Network, but Umbridge and the Inquisitorial Squad stops them before they can do so. When she threatens to use the Cruciatus Curse to get information out of Harry about the trio's intentions, Hermione deceives Umbridge into entering the Forbidden Forest in search for Dumbledore's "secret weapon". She and Harry lead her to the hiding place of Hagrid's half-giant brother, Grawp, only to be confronted by centaurs who kidnap Umbridge after she attacks them. Harry, Hermione, Ron, Luna, Neville and Ginny fly to the Ministry of Magic on Thestrals in an attempt to save Sirius. Which was a little shock for Neville, Ginny, Hermione and Ron, because Thestrals only can be seen by people who have witnessed death.

Afterwards, the trio, Neville Longbottom, Luna Lovegood and Ginny Weasley head to the Ministry of Magic, where they go to the Department of Mysteries and look for the prophecy of Harry Potter and Lord Voldemort. However, many Death Eaters, including Lucius Malfoy and Bellatrix Lestrange ambush them. Lucius says that "you only saw what he wanted you to see", confirming Hermione's hunch. A short battle ensues, and the Death Eaters take hold of everyone but Harry, threatening to kill them if he does not surrender the prophecy. Harry proceeds to hand the prophecy over to Lucius, but is interrupted when Order members (Sirius Black, Kingsley Shacklebolt, Remus Lupin, Nymphadora Tonks, and Alastor Moody) arrive to defeat the Death Eaters. In the midst of the battle, Lucius drops the prophecy. Shortly after Sirius disarms Lucius, Bellatrix strikes him with the Avada Kedavra curse. Devastated and infuriated, Harry chases Bellatrix out to the Atrium and attempts to torture her with the Cruciatus Curse, but fails due to not possessing real cruelty, despite Voldemort's urges. Voldemort appears to finish him off, but Dumbledore arrives via the Floo Network to save Harry. A short battle ensues between Voldemort and Dumbledore, and Bellatrix escapes. Dumbledore overpowers Voldemort, and Voldemort attempts to possess Harry, but Harry manages to overcome his powers due to Harry's love for his friends and Sirius and claims that Voldemort is the weak one; Voldemort will never feel true love or friendship. Just as Voldemort disapparates Ministry officials arrive and Cornelius Fudge is forced to admit that the Dark Lord is indeed back in power. He resigns as minister. Lucius Malfoy was sent to Azkaban. As Dumbledore's Army and Dumbledore return to Hogwarts and Dumbledore is reinstated as headmaster, Dumbledore and Harry discuss the prophecy, and Harry discovers that in the end, only one can live, and that he and Voldemort are destined to fight each other.

Mistakes

When Harry and Mr. Weasley are going on the Underground, Mr. Weasley tries to get through without his ticket. You can see Harry pulling his ticket out of his pocket when the camera is behind them. When the camera goes in front of them, Harry puts his hand in his pocket again. The camera goes behind them - and Harry pulls his ticket out another time.

When the Dursleys bring the ill Dudley out and into the car, the flowers behind them are large and white. Later, when the Advance Guard leave with Harry, the flowers are small and red.

When Harry and Mr. Weasley are about to enter the Ministry of Magic/telephone booth, the pavement they walk on is dry but when they are in the telephone booth, they show the same pavement which now has a puddle on it.

In the thestral scene, Luna is clearly stated in bare feet, however, she is later seen wearing white trainers, then she is barefoot again.

When Harry has his first nightmare that is seen, during the nightmare he is wearing a light blue T-shirt. However, when he wakes up and sees Ron, he is wearing a dark blue polo top with a button on the collar.

During the D.A. montage it is made a clear point that Neville cannot produce an Disarming Charm. Then at the end of the scene Neville is seen knocking a wand out of Parvati Patil's hand. This causes excitement from the rest of the group. However, when they are seen casting spells at the model Death Eater, Neville produces a very good Disarming Charm that knocks the model across the room. Neville was probably trying to disarm it not send it flying.

During the O.W.L.s when Umbridge walks to the door, she walks past Harry, and then Neville. However, in the next scene, Neville is shown to be sitting in front of Harry.

Differences between book and film

1. Dudley Demented

Dudley's gang of friends is with him when Harry confronts Dudley. In the book, they had left to go home, so Dudley and Harry are alone. In the video-game adaptation, Harry speaks to Dudley after hearing everyone of Dudley's gang saying goodbye to Dudley.

2. A Peck of Owls

In the book, after Harry explains how Dudley was attacked by a Dementor, and Vernon asks what that is, Petunia blurts out the explanation, leading both Harry and Vernon to wonder how she knows this. This is nowhere in evidence in the film, and some plot points in Deathly Hallows may be confusing if filmed as a result.

3. The Advance Guard

Tonks' status as a Metamorphmagus is never even discussed in the film, though her hair does turn red when Mad-eye calls her by her first name. She starts changing her nose at the dinner table without any real explanation of her powers.

Nymphadora Tonks's name is only mentioned twice in the film, both times by Alastor Moody. Also, she does not appear to have a close relationship with Harry Potter as she did in the books. They don't directly talk to each other. Although, she winks at Harry as she walks by him upon arriving at Grimmauld Place.

In the film, the Advanced Guard arrives to remove Harry from Little Whinging right after the Dementor attack. In the book, Harry is grounded for days until the Advance Guard comes.

In the film, when Harry and the Advance Guard fly by brooms, they fly up the Thames; in the book, they fly at much higher altitude to avoid detection by Muggles.

Remus Lupin, Dedalus Diggle, Sturgis Podmore, and Hestia Jones are omitted from the Advance Guard, reducing it to Alastor Moody, Kingsley Shacklebolt, Nymphadora Tonks, Elphias Doge, and Emmeline Vance, the latter two who have no lines. Lupin does appear later in the film, but gets little screen time. Sturgis Podmore is not featured in the film, and his being sent to Azkaban is omitted.

4. Number Twelve, Grimmauld Place

The details regarding Bill Weasley's moving back to England to be closer to his family with his new position in the Order of the Phoenix and Charlie Weasley being in charge of recruiting foreign wizards to the Order has been omitted. Additionally, unlike Bill who would later appear in the film adaptations of Harry Potter and the Deathly Hallows, Charlie was never acknowledged as a member of the Order in the films.

Percy Weasley's standing with the Ministry of Magic is sudden and unexplained, and there is no mention of him disowning his family when he chose to support the Ministry. This creates a large plot hole in the film due to his disposition towards Harry being unexplained, making it confusing for the viewers who did not read the book.

In the novel, Harry yells at Ron and Hermione about everything he has done when they mention what Dumbledore told them about not telling Harry anything. He mentions saving the Philosopher's Stone, killing the Basilisk, fighting the dementors in the third year, getting through the maze, and fighting off Voldemort. In the film, he does not yell, and his rant is restricted to one single line: "I'm the one who saw Voldemort return, I'm the one who fought him, I'm the one who saw Cedric Diggory get killed."

5. The Order of the Phoenix

Nymphadora Tonks changes her hair into violet, bubblegum pink, tomato-red, grey and blonde. Also, in the book, her main colour of hair is bubble-gum pink, but in the film it is switched to purple and it stays that way throughout the film. However when Harry is picked up from the Dursleys, Moody calls her Nymphadora and as she angrily tells him not to do that, her hair turns red briefly, but then their brooms arrive and her hair turns back to purple again. This suggests in the film, her hair changes colour when she is feeling a particuarly strong emotion. However, at 12 Grimmauld Place, she changes her nose to a pig's snout.

6. The Noble and Most Ancient House of Black

Kreacher's role is diminished to only two scenes: Him speaking to the Walburga Black's portrait (Which is where Harry first sees him) and when he makes insulting comments to Harry. It is also never explained that he gave information to Narcissa Malfoy. In the book, Kreacher is introduced to Harry by Hermione in front of all the Weasley children.

In the novel, Sirius tells Harry his family's back story and him being disowned shortly after Harry arrived at Grimmauld Place. In the film, he tells him this during Christmas, where Harry's Christmas party with the Weasleys took place at Grimmauld Place instead of St. Mungo's.

7. The Ministry of Magic

In the book, Mr. Weasley is told by Perkins that Harry's hearing has been changed. In the film, Mr. Weasley is told by Kingsley Shacklebolt. Also, in the book, they were late for the hearing. Additionally in the film, when Harry asks when the hearing starts, Mr. Weasley says, "In five minutes," while in the book he says, "We should have been there five minutes ago!".

8. The Hearing

Albus Dumbledore does not produce a chintz armchair out of air. He just keeps standing and then Arabella Figg is seen sitting on Harry's chair and Harry is seen sitting on the balcony.

Amelia Bones being impressed by Harry's ability to conjure a Patronus is omitted, although she still votes in clearing him of all charges.

There's no mention of Mrs. Figg being a Squib, but it is known that she lives in Privet Drive rather than Wisteria Walk.

During the hearing in the book, Cornelius Fudge's line "Laws can be changed" is said after Dumbledore says that the Ministry does not have the power to expel Hogwarts students nor confiscate wands. In the film a similar line "Law can be changed if necessary, Dumbledore" was used after Dumbledore mentions that magic may be used before Muggles in life-threatening situations, thus the film portrays him as a tyrant.

9. The Woes of Mrs. Weasley

In the film, Harry encounters Lucius Malfoy before his trial, not after, but they also do not confront each other and speak with mutual hatred.

In the book, Mad-Eye Moody shows Harry a picture of the original Order of the Phoenix in No. 12 Grimmauld Place. In the film, Sirius shows him the picture in a back room at King's Cross.

Harry and the others cleaning Grimmauld Place is omitted, and as such, Harry going to the hearing occurs the day after he arrives at Grimmauld Place, and after the hearing Harry is next seen at King's Cross to go back to Hogwarts. This omission also removes the event involving the discovery of Salazar Slytherin's locket, which does not prove to be important until the 7th book and film.

In the book, there is a scene during the party at 12 Grimmauld Place where we see Mrs. Weasley attempting to excise a Boggart from one of the dressers upstairs. Therefore, it is not revealed that Mrs. Weasley's worst fear is that her family (and Harry) will die.

Hermione Granger and Ron Weasley becoming prefects is omitted from the film. In the film, Harry goes with Ron and Hermione on the Hogwarts Express, implying they did not become prefects, as in the book, he went with Neville, Ginny and Luna Lovegood as Ron and Hermione sat in the prefects carriage.

10. Luna Lovegood

When Harry, Ron, and Hermione first see a Thestral, Neville is with them. Neville shows no sign of being able to see the Thestral even though he can see Thestrals in the books.

In the book, Harry meets Luna Lovegood on the Hogwarts Express, but in the film they meet her on a carriage. Also, in the book it was Ginny who introduced them to Luna, but in the film, it was Hermione, even though she did not know Luna in the book.

11. The Sorting Hat's New Song

The Creevey brothers are not featured in the film. However, the character Nigel Wolpert, who is not in the books seems to serve as a replacement.

In the book, Harry and Seamus have their argument in the Gryffindor boys' dormitory in front of Dean Thomas and Neville before Ron enters and tells Seamus off. In the film, Harry and Seamus argue in the Gryffindor Common Room in front of boys and girls before Ron enters. Also, in the film, there is no mention of Harry and Ron having met Mrs. Finnigan since she was omitted from the previous movie.

It is shown in the book when Ron comes to break up the fight between Seamus Finnigan and Harry Potter he says he is a prefect and nobody should mess around. However in the movie it just says that the fight should stop.

Dolores Umbridge's uniform black bow is omitted from the film. Also, Umbridge wears a green tweed cloak in some parts of the book, but in all the film except Harry's hearing, she wears pink cardigans.

Seamus and Harry fighting.

12. Professor Umbridge

The scene where Umbridge tells Harry to give McGonagall the note about his behavior in class is omitted and so is the rest.

13. Detention with Dolores

In the film, Umbridge seems to show some remorse about forcing Harry to write lines in his own blood, whereas in the book she seems delighted at the chance to punish him.

Harry is seen only in one detention. The rest of his detentions are omitted.

14. Percy and Padfoot

The Quidditch season is removed entirely from the film, as well as Ron joining the team as Keeper, Umbridge removing Harry, Fred, and George from the team, and Ginny joining the team to replace Harry. This later creates a bit of a plot hole, as while Ron tries out for the team in the next film, Ginny doesn't, but still appears to hold a position of some seniority. Because of the omission, Angelina Johnson and her fellow chasers Katie Bell and Alicia Spinnet are also cut.

Due to the omission of Percy defecting from his family, him sending Hermes to deliver to Ron the letter to stop associating with Harry is omitted.

15. The Hogwarts High Inquisitor

The producers also included another scene where Umbridge is walking down a corridor and she waves her wand and a girl and a boy stop kissing also she waves her wand again and she tidies up three boys that walk past her.

16. In the Hog's Head

As in the previous two films, Ginny's role is diminished, and nothing of her relationship with Michael Corner is ever talked about though they are seen together at the meeting in the Hog's Head where Harry, Ron, and Hermione form Dumbledore's Army.

Zacharias Smith is not named in the film. Instead, he as known as "Somewhat Doubtful Boy" during the credits. In the films, Zacharias seems to be portrayed as a much less obnoxious person.

17. Educational Decree Number Twenty-Four

Harry taking Hedwig to see Professor Grubbly-Plank to mend her wing, including finding Sirius' letter attached to Hedwig's leg was not in the film. (Grubbly-Plank's role in the film was practically nonexistent)

Sirius visiting the trio through the fire in the Gryffindor Common Room, when Umbridge's hand comes through was also cut from the film.

18. Dumbledore's Army

Dumbledore's Army

In the film, Hermione has heard of the Room of Requirement; whereas, in the book she has not.

In the book, after the kiss between Cho and Harry, Hermione gives a much longer list of reasons why Cho was crying, including her being worried about getting kicked off the Ravenclaw Quidditch team. In the film, the list is shorter, but Hermione says that Cho is worried about failing her O.W.L.s, but Cho in the books is stated as a year ahead of Harry, so she should have taken her O.W.L.s already. Also, Hermione mentions that Cho's mum worked at the Ministry, even though it was Marietta Edgecombe's mum who worked at the Ministry. However, as Marietta was cut, her parts had to be taken by Cho.

A new scene is added in the film where Argus Filch notices students going in the Room of Requirement and holds a vigil outside.

19. The Lion and the Serpent

20. Hagrid's Tale

In the novel, during a Care of Magical Creatures class, Hagrid tells Harry about Thestrals, but in the film, Luna Lovegood tells him about them in a fabricated scene.

21. The Eye of the Snake

In the novel, after Harry wakes up from seeing the vision of the attack, Neville goes to fetch McGonagall. This is omitted from the film.

Straight after he witnesses Nagini's attack on Arthur Weasley, Harry Potter has his first Occlumency lesson with Snape in the film, but in the book, he takes a Portkey back to Grimmauld Place and is told about Occlumency there later during the holidays before Sirius and Snape start an argument which didn't happen in the film.

23. Christmas on the Closed Ward

In the novels, Harry finds out about the condition of Neville's parents from Albus Dumbledore significantly before Neville's other friends learn of it. In the film, Sirius tells Harry how they suffered a fate worse then death, and Neville later tells Harry more in the Room of Requirement.

24. Occlumency

In the book, when asked if Voldemort can read minds, Snape goes into a long explanation that "Mind reading" is not a good term to use for wizards. In the film, when Harry asks if Voldemort will be able to read his mind, Snape simply says, "Read it. Control it. Unhinge it," not going into the explanation about the term.

25. The Beetle at Bay

Rita Skeeter was also omitted from the film. In the book, Hermione blackmails her into writing articles that support Harry as the rest of the Wizarding world denies his claims, as well as him being sent dozens of mail. Instead, Seamus believes Harry when he looks at the paper with the Azkaban breakout.

26. Seen and Unforseen

In the film, Hagrid mentioned that the reason for the Centaur's anger towards humans was because the Ministry of Magic was taking away their lands. There was also a Daily Prophet headline that was used in the film that supported this "MINISTRY ANGERS CENTAURS". In the book, it was because Firenze had taken up the post of Divination teacher, and the centaurs were angry that he was giving away their secrets to his students, combined with that Grawp was living in the forest who was disturbing their habitat.

In the book, Hagrid comes back from the giants' world in around the beginning of the second half of the book, but in the film, he comes back late in the film.

In the film, Harry does not see Snape's father, Tobias yelling at Snape's mother, Eileen Prince, while a young Severus Snape is seen crying in the corner. Although, when Harry breaks into Snape's memory, there is one vision of a young Snape sitting in a corner crying, but it is unknown if it was that scene.

In the book, Sybill Trelawney is sacked during one of Harry and Snape's Occlumency lessons after the Christmas holidays, but in the film she was sacked before Harry learned about Occlumency and before the Christmas holidays.

27. The Centaur and the Sneak

In the book, Dobby comes to tell Harry that Umbridge and her Inquisitorial Squad are coming. In the film, Nigel looks through a hole in the wall and that is how Harry finds out.

In the book, during Fudge's discovery of Dumbledore's Army, Dumbledore was sitting behind his desk while in the film he was sitting on his desk.

In the film during the scene in Dumbledore's office, McGonagall is not present, unlike in the book.

In the film, Fudge and everybody enters Dumbledore's office when Harry is dragged there, unlike in the book where they are waiting until Umbridge arrives with Harry.

In the novel, Dumbledore's Army is discovered because Marietta Edgecombe, a member and a friend of Cho Chang, tattled to Umbridge. In the film, Cho is duped into revealing the truth via Veritaserum, and Umbridge and the Inquisitorial Squad break into the Room of Requirement using "Bombarda Maxima," which did not happen in the book. Also, in the film, this is used as a reason for her and Harry's break-up.

In the book, after Dumbledore escapes, Phineas Nigellus Black states, "You know, Minister, I disagree with Dumbledore on several points, but you can't deny, he's got style." In the film, Kingsley Shacklebolt says a similar line: "You may not like him Minister, but you can't deny... Dumbledore's got style."

When Cornelius Fudge arrives to arrest Dumbledore in the film, Dumbledore disappears by clapping his hands onto Fawkes and disappearing in a flourish of fire. In the novel, Dumbledore knocks out Fudge, Umbridge, Dawlish, and Kingsley Shacklebolt, but still escapes using Fawkes before the others regain consciousness. Also, in the novel, Percy leaves the room before Dumbledore knocks everybody (except Harry and McGonagall) out, so he doesn't become unconscious, but in the film, he remains in Dumbledore's office along with everyone else and sees Dumbledore disappear.

28. Snape's Worst Memory

In the film, all Dumbledore's Army members are seen having detention in the Great Hall, under the sight of Umbridge. The detention is just the same as Harry's with the Blood Quill. In the book, this scene does not exist.

In the film, Harry saw his father (both parents in the book) in the flashback by using the Protego spell to Prof. Snape instead of looking at the memory through the Pensieve. Young Lily Potter is also cut from the film, even though she was cast for the film.

In the book, Harry sees Snape being harassed by James and Sirius via Snape's Pensieve, while in the film, Harry casts a shield against Snape's Legilimency spell and sees Snape's memories. Also, in the film, it is only James that bullies Snape while Sirius just watches amusedly.

In the book, members of the Inquisitorial Squad had additional powers such as docking points even from Prefects. This is only shown when Umbridge gives them their badges.

In the book, Umbridge and McGonagall row about how she punishes students during Harry's career guidance meeting and also have a minor disagreement during class inspections. In the film, the two row on the Grand Staircase and McGonagall's class inspection is omitted completely. As the Weasley twins' diversion is cut from the film, another scene is also cut, where Harry uses Umbridge's Floo Network connection to contact Sirius and Lupin at Grimmauld Place to consult them about their treatment of Snape when they were all students at Hogwarts.

In the book, Prof. Umbridge and Filch are seen using spells to try and stop the firecrackers, but in the film, they do nothing but run and scream, duck and dodge. In the book, the twins were never on broomsticks, and the scene lasted much longer.

Fred and George Weasleys' departure from Hogwarts is done differently from the book. In the book they first send out their enchanted fireworks to cause a disturbance and later caused another disturbance to give Harry time to sneak into Umbridge's office to use her Floo Network and then flee after being cornered by Umbridge. In the film, the Weasley twins leave after releasing their fireworks.

30. Grawp

Grawp is portrayed as very gentle, whilst in the book he is very violent and even strikes his half-brother Hagrid in the face during his appearance.

In the book Harry and Hermione were introduced to Grawp by Hagrid while the school was distracted by the Quidditch final of Gryffindor vs. Ravenclaw, while in the film Ron was also present, because there was no Quidditch in the film.

31. Owls

In the book, Cornelius Fudge's Aurors and Dolores Umbridge try to take Hagrid away, and as a result, Professor McGonagall gets hit by four stunning spells, and gets taken to St Mungos. This scene was reportedly filmed, and a set photo shows McGonagall in a wheelchair reading a newspaper; however, it was edited out of the final cut.

McGonagall is not injured, as the scene where Hagrid is driven away is omitted, however a deleted scene shows her in a wheelchair.

In the book, several weeks elapse between the Weasley twins leaving, and the O.W.L. Exams where Harry sees the vision of Sirius being tortured at the Ministry of Magic during the exams. In the film, these occur one after the other, on the same day, along with Harry, Ron, and Hermione getting caught by Umbridge trying to use her Floo Network connection.

There are a lot more Educational Decrees in the film when compared the book, often having ridiculous rules that were invented for the film. Also in the film, due to the very large number of Decrees, it completely covered the wall they were posted on, and that all of them were destroyed when Fred and George Weasley released their enchanted fireworks during their escape from Hogwarts.

In the book Fred and George Weasley suggest to Harry that he should use the Floo Network from the fireplace in Umbridge's office to connect to Grimmauld Place after Umbridge told Harry that it is not under observation by the Ministry. In the film however, Harry figures it out on his own and mentions it to Ron and Hermione as he is heading down there.

32. Out of the Fire

In the book, Ron, Ginny, Luna and Neville get out of Dolores Umbridge's office a different way. In the book, Ron mentions that they got out using several spells. However, in the film it is Ron who tricked the Inquisitorial Squad into eating some Puking Pastilles. Also in the book, Ron, Ginny, Luna and Neville meet Harry and Hermione in the Forbidden Forest while in the film they meet on the Covered Bridge.

In the film, Kreacher never tricks Harry into searching the Ministry for Sirius.

In the book, the members of Dumbledore's Army that come with Harry are mentioned to be bound and gagged after being caught. In the film Luna, Neville, Ginny, Ron and Hermione are not forced to enter inside Umbridge's office in the mentioned state.

In the book, after being caught by Umbridge during his attempt to break into her office she revealed to Harry and his friends that she had sent the Dementors to Harry discreetly without Fudge's knowledge as a way to discredit Harry. In the film, the one responsible is a mystery, though during the Wizengamot scene Dumbledore speculated it could have been Voldemort.

In the book and the film, Umbridge catches Harry using her fireplace to connect with Sirius, But in the book, he denies it twice, making Umbridge call him a liar twice and shove him away from her. In the film, Harry denies it once, making Umbridge call him a liar once and slap him across the face.

33. Fight and Flight

In the book, when going to the Ministry of Magic on Thestrals, Luna Lovegood rides side-saddle. In the film, she rides as the rest of the party does.

When the centaurs take Umbridge away, they pay no attention to Harry or Hermione, while in the book they attack them as well. Also in the film Grawp is present as the centaurs attack Umbridge, and picks her up before they take her away, while in the book he arrives as the centaurs are about to take Harry and Hermione away. There is also no mention of how Umbridge got out of the forest; the only time she appears afterwards in the film is when a Daily Prophet shows her packing up after being fired.

34. The Department of Mysteries

In the film, a large number of the rooms Harry, Ron, Hermione, Luna, Neville, and Ginny had to go through, before finding the Hall of Prophecy, were left out.

35. Beyond the Veil

In the book, Harry, Ron, Hermione, Ginny, Neville, and Luna all use Reducto on the shelves in the Hall of Prophecy to break them and distract the Death Eaters. In the film, this is caused by Ginny using Reducto on a Death Eater (possibly Avery or Mulciber).

In the book, the Death Eaters do not Apparate inside the Ministry of Magic as they do in the film. Apparition in the film seems to turn the Death Eaters into a fast moving smoke rather than real teleportation, while Order members turn into a stream of silver steam instead. Fred and George seem to Apparate the same way as in the book.

In the film, when fighting a Death Eater in the Hall of Prophecy, Luna is seen to use levicorpus, a spell which Harry discovered in the former potions textbook of potions master Severus Snape in his sixth year, after the events of the fifth book. Luna should not know of the spell as such. Furthermore, the effect of levicorpus in the film is different to that in the book. In the film, Luna uses levicorpus to send the Death Eater flying backwards. In the book, Harry accidentally uses the spell on Ron to leave him dangling in mid-air by one of his ankles.

In the film, Albus Dumbledore appears in the Ministry Atrium after Sirius's death, but in the book, he is spotted by Harry and Neville in the Death Chamber before Sirius dies.

In the film, Bellatrix Lestrange kills Sirius Black with the Killing Curse, which then causes Sirius' body to fade away into the veil in the Death Chamber. In the book, the curse is not named and is not even implied to have been the Killing Curse.The Killing Curse causes a green light whereas the light that came from Bellatrix was red and non-verbal, suggesting it was a mere Stunning Spell or an Impedimenta Jinx.

In the novel, Ron, Hermione, Luna, Neville, and Ginny fight and flee from the Death Eaters during the battle, instead of being captured by them, as they are in the film.

In the film, after killing Sirius, Bellatrix gives a very brief look of remorse before breaking into a smile.

In the film, after Harry gives Lucius Malfoy the prophecy, Sirius says to Lucius "Get away from my godson!" and punches him in the face, which never occurred in the book, though Sirius did do a fairly similar thing to Antonin Dolohov.

In the book, the archway has a veil, whereas in the film it has a sort of mist.

In the film, Sirius mistakenly calls Harry by the name of "James." This does not happen in the book; it is only debated that Sirius views Harry as a pal in the same way he viewed James Potter.

Harry was seen casting a nonverbal spell. However, in the sixth book Harry was said to have difficulty with nonverbal spells.

Harry Potter and the Order of the Phoenix - Ministry of Magic

36. The Only One He Ever Feared

In the book, Bellatrix Lestrange talks to Harry about the Cruciatus Curse, saying he has to mean it. In the film, Voldemort talks to Harry, telling him what Bellatrix did in the book,and prompting him to use it.

In the book, Dumbledore uses the Fountain of Magical Brethren to protect Harry while duelling Voldemort, and Fawkes takes a Killing Curse for him. In the film, only Dumbledore protects Harry and does not use the Fountain.

Lord Voldemort's conjuring or even having the Silver Shield is omitted.

37. The Lost Prophecy

In the film, after the Battle of the Department of Mysteries, a Daily Prophet article mentions on Fudge possibly resigning from his post. In the book however the Daily Prophet that was released after the incident did not mention anything about Fudge's possible resignation and it wasn't until the following book that would reveal that Fudge had lost his job as the Minister for Magic after the incident.

In the book, Harry Potter loses his temper with Dumbledore after Sirius Black's death and smashes his possessions, which did not happen in the film.

In the film, Dumbledore's explanation of the prophecy is diminished to just one word, when he confirms to Harry that either he or Voldemort will have to kill the other. He doesn't explain the prophecy could refer to either Neville or Harry, that it was because of the prophecy that Voldemort killed Harry's parents, or that Voldemort had gained knowledge of part of the prophecy shortly after it was made and the reason he so desperately wanted to have possession of it was to hear it entirely, so that he could find out how to destroy Harry.

In the film, Harry never learns that it is Sybill Trelawney who made the prophecy, in fact the scene where Dumbledore shows Harry his memory of being told the prophecy in the Pensieve is omitted. Whereas in the film, Harry hears the prophecy come out of its orb as soon as he touches it in the Hall of Prophecy. The prophecy does, however, speak in Trelawney's voice.

38. The Second War Begins

Harry receiving a two-way mirror as a present from his godfather Sirius Black shortly before his death that would had allowed him to communicate with Sirius if he had not died was removed.[1]

Nearly Headless Nick is omitted and the important part where he explained to Harry that not all wizards can come back as ghosts. This scene was originally filmed, but cut to make the films shorter. [1]

In the novel, Luna tells Harry that her mother died when she was 9 years old when Harry finds her pinning up notices of her lost things, but in the film, she tells him about her mother's death in the Forbidden Forest where she also tells him about Thestrals.

In the film, there is a scene in which Harry and Luna notice a pair of sneakers hanging from an archway when Luna is putting up her notices.

Draco Malfoy's new found hatred for Harry Potter due to his father's arrest has been omitted and instead would not be mentioned until the following film. Therefore, the scene where Harry tries to curse Malfoy, Snape takes 10 points from Gryffindor and McGonagall returns to Hogwarts and awards Gryffindor 250 points and Ravenclaw 50 points for the battle in the Department of Mysteries is also omitted.

Harry's visit to his friends in the Hospital wing and to Hagrid in his hut is omitted.

Behind the scenes

The company which created the film trailer entitled Divine Crusade is X-Ray Dog.

In Snape's memory, Hogwarts students are seen wearing uniforms of the same design as the uniforms used in the first two films. This gives a reason in the story for the different uniforms from the second film to the third film despite the real reason being the change of direction.

During production of the film, several cast members including the core trio of Radcliffe, Watson and Grint filmed a mini-adventure entitled The Queen's Handbag for broadcast during a celebration of Queen Elizabeth II's 80th birthday.

Over the opening shot of the Warner Bros. logo, the voice of Nagini can be heard, speaking Parseltongue.

The only scene involving Harry Potter and Draco Malfoy is when Harry gets off the Hogwarts Express

Only appearance of the London Underground Station.

Director David Yates stated in an interview that he had originally shot a three hour film for Order of the Phoenix. However, some material had to be cut out in the final edit, as the film was 45 minutes too long. [2] Therefore, several locations which were used for various scenes, do not appear in the final cut of the film. In Verginia Water, scenes were shot where Professor McGonagall recovers from Stunning Spells,[3] and Burnham Beeches was used for filming the scene where Hagrid introduces his fifth-year Care of Magical Creatures class to Thestrals.[4] Harry skips stones in front of Bonnie Prince Charlie's Monument in Glenfinnan in another cut scene.[5]

Because Quidditch is absent in the film the only scenes involving the use of a broomstick is when Harry departs from Privet Drive and when Fred and George leave the school.

Dolores Umbridge appears briefly in Half-Blood Prince repeating her line, "I will have order!" from this film.

Second time Dumbledore announces a reminder from Mr. Filch (interrupted by Umbridge).

Harry is (briefly) expelled from Hogwarts in the book; in this film he returns after he is cleared of all charges.

At 132 minutes this is the second shortest film (next to Harry Potter and the Deathly Hallows: Part 2) despite it being the longest book.

The interior set for 12 Grimmauld Place was reused as the residence of Sherlock Holmes, 221B Baker Street, in the 2009 Guy Ritchie film (also a Warner Bros. film).

The scene when Dumbledore uses a spell that makes water surround Voldemort inspired the makers of the 2010 film The Last Airbender.[6]

After the title appears, an orb, much like the prophecy-orbs can be seen which then changes into the sun as to transition from the title clip to the film.

If the subtitles are on when Harry gets a letter from the Ministry and an owl hits the wall it says "Hedwig Screeches" though the owl is not Hedwig.
